基于微机保护测试仪的系统故障分析与微机保护配合实验

目前各级供电公司培训学员多只针对保护装置本体校验,而缺乏对系统故障时各保护装置之间配合情况的了解和认识,本文通过试验方式详细阐述了线路差动保护死区故障时母线保护、线路保护之间的配合,并完整的分析和记录保护动作的行为、实验数据及实验过程中遇到的实际问题,借此提出继电保护培训的新思路,供同行参考。

System Fault Analysis and Computer Relay Protection Matching Experiment Based on Microcomputer Relay Protection Tester

At present,most trainees of power supply companies only focus on the check of protection relay experiment,thus the matching between each protection experiment as the fault happens is ignored.This paper presents the matching between busbar protection and transmission line protection as the fault happens in the dead zone based on the transmission line differential protection,at the same time the protective action,experimental data and the problem during the process of experiment are analyzed and recorded.Fina...
